Declare snd_soc_codec_driver structures as const as they are only passed
as an argument to the function snd_soc_register_codec. This argument is
of type const, so declare the structures with this property as const.
In file codecs/sn95031.c, snd_soc_codec_driver structure is also used in
a copy operation along with getting passed to snd_soc_register_codec.
So, it can be made const too.

The es7134 is 24bit, 192Khz i2s DA converter for PCM audio.
Datasheet is available here : http://www.everest-semi.com/pdf/ES7134LV%20DS.pdf
This driver is also compatible with the es7144, which is the same as the
es7134, with 2 additional pins for filtering capacitors.
